' 1 citizenuof the United .1345 it'known that I, OMER C. BARen-R, a

of Indianapolis, county of Marion, .and State of Indiana, have inventeda certain new and. useful Insulator; and I- do hereby declare, th'atthe following is a full, clear,

I and exact description thereof, 'referencebeinsulators,

This invention provlsion of extensions above and ibelowthe shield and axial therewith, said extensions having radial ribs at their free, ends. further feature of the invention is the provision of hangersfor engagement with the extensions, said hangers 7 being preferably formed in sections and bolted in engagement with the extension :provision of cars on the hangers, the 'ears" one hangerv being-placed fac'e'to face.

A further feature of the invention is the of against each other so 'asto form a; tongue which is designed to be entered between the ears of the otherhangerwhich are placedseparated position, so that-any number of insulators may be secured together."

To more securely guard against the curthe surface of the shield 2, so as to form a circuit vided with ,aplurality of depending concentric ribs '21 which, are of considerable depth, thereby creating an unusually extended surface over which the current would have 'to travel before passing from one hanger to the other. By providing the hangers in sections, they can more readily be attached to or removed tion of the insulator, and by providing the between the hangers and the glass portion of theinsulator, all-possibility of breaking or in any the glass insulator is obyifrom the glass; poi

,ated, and likewise the cushioning InaterI-alwill permit the contraction or expansion of the parts of the insulator without danger of injury to the glass portion thereof.

It will likewise be seen that this device can be very cheaply constructed and quickly asthe shield portion I the ears 19 being jadapted'to extend between the; ears 18 of the next adjacent hanger, and by' extending a between the hangers v 7 and 8, the under face-of the shield 2 is prosection extendlng flatwise senibled together and theta battery of the insulators may applied to use.

It will likewise be seenthat by forming the extensions of considerable length beyond of the insulator, and by providing a plurality of concentric ribspn the lower face of the shield, 'all possibility of the current passing around the glass pore ltion of the insulator from one hanger to another is entirely. obviated.

' The invention claimed is I An insulator construction, includinga shield, extensions on each side of the'shield,

a rib atthe outer end of ,eachextension,

hangers formed of a pair of substantially semi-cup shaped nielnbers, an inwardlyextending fiangefat the open ends of said mem-.

bers adapted to engage said ribs, a bolt extending transversely through each pair of of the companion hanger being fiatwise to the meeting edges of the, sections and placed a distance apart to receive the ears forming the single element, and means for p-ivotall'y, securing the ears of one hanger to the ears of the next succeeding hanger.

In witness whereof, I have hereunto afiixed my signature in the presence, of the witnesses herein naihed.
